Zusammenfassung: | A polyurethane polymer, a synthetic leather including such polymer, and a method of making such polymer, wherein the polyurethane polymer includes the reaction product of components including: a fluorinated mono-functional alcohol comprising a perfluorinated (C4-C6)alkyl group, a perfluorinated (C4-C6)alkylene group, or both; a fluorinated aliphatic diol comprising a perfluorinated (C4-C6)alkyl group, a perfluorinated (C4-C6)alkylene group, or both; a hydrocarbon diol; and a diisocyanate; wherein at least one of the following conditions is met: the total of the fluorinated aliphatic diol and the mono-functional alcohol is less than 2 wt-% of the components forming the polyurethane polymer; or the total fluorine content is less than 1 wt-% of the polyurethane polymer. |
